Arrived within 48 hours of ordering. The cap comes with instructions to help collimating but it’s a very simple premise. Would appear my scope is still perfectly collimated (which was bought from FLO in April).

Good quality! Will be the first time ever for me using this in combination with the premium Cheshire from FLO. 👍🏻

Brought this to use alongside the premium Cheshire and it works brilliantly, great service again from FLO thanks guys

Great product, received very promptly and seems to have done the trick without forking out for much more expensive collimation tools! Thanks FLO!

Did it's job well. Very easy to use. Great value and delivery.

I find this is all you need to collimate the primary and secondary mirrors of my Skywatcher 200p Newtonian.

It may just be me but as a spectacle wearer I can find it awkward to keep my eye correctly positioned and the edge of the primary in the field of view when using a Cheshire (it usually ends up as one or the other). Because the Aline cap lets me get my eye closer to the focus tube I find it makes it much easier to see that the primary is correctly centred. I still use the Cheshire, as I find the crosswires help with the fine tweeks, but the Aline cap is so quick and simple to use as a check of the basics before and after using the Cheshire.

It's a collimation Cap, so not a lot more I can say other than it worked as expected and the item arrived quickly with the usual great service from FLO.

Extremely fast delivery of a great little device that makes basic collimation a breeze!

Firstly, FLO service, perfect ad normal.

This Aline works well and does exactly what it claims. Easy to use, but still comes with instructions.
